After voicing her support for Paul, and taking heat on Twitter in the process, Clarkson's latest album, Stronger, is going gangbusters on Amazon, spiking 200 percent in sales on the e-tailer within a 72-hour period, according to the website.

Earlier this week, Clarkson sparked outrage when she professed her admiration for Paul on her Twitter and WhoSay accounts, posting: "I love Ron Paul. I liked him a lot during the last republican nomination and no one gave him a chance. If he wins the nomination for the Republican party in 2012 he's got my vote. Too bad he probably won't."

Immediately after the tweet, a firestorm of negative feedback from Clarkson's almost 1 million followers on Twitter. Many of the singer's fans claimed Paul has tolerated homophobia stemming from newsletters he alleged penned in the 1970s and '80s.

"Man my eyes have been opened to so much hate tonight," Clarkson responded on Twitter. "If y'all ever disagree with something I say please don't feel the need to attack me. I will listen to what you say and any articles or viewpoints you have when you say it with respect. Being hateful is not a healthy way to get people to see or hear you."

Clarkson, who won a Grammy Award in 2006 for her debut album (which spawned the No. 1 hit "Since U Been Gone"), released Stronger in October. It debuted on the Billboard 200 at No. 2 with its lead single, “Mr. Know it All,” peaking at No. 4 on the Hot 100. Clarkson, who's set to go on tour in a few weeks, was honored with a CMA Award during the Nov. 9 ceremony for “Don’t You Wanna Stay,” her hit collaboration with Jason Aldean.
